摘要： A fixing device includes: a cylindrical film; a nip forming member; and a back-up member for forming a nip. The nip forming member includes a projected portion. The projection amount of the projected portion is smaller in an end portion region positioned at an end portion of the projected portion with respect to a generatrix direction of the film than in a central region positioned at a central portion of the projected portion with respect to the generatrix direction, at least a part of the end portion region being inside a feeding region of a maximum-sized recording material usable in the fixing device. With respect to the recording material feeding direction, the width of the part of the projected portion inside the nip is broader in the end portion region than in the central region.

摘要： An image heating apparatus includes an image heating portion including a heater, a tubular film having an inner surface in contact with the heater, and a pressure member that is in contact with the outer surface of the film and forms a nip portion for conveying a recording material between the outer surface and the pressure member. The image heating portion heats an unfixed toner image on the recording material by the heater. A temperature detection portion detects the temperature of the heater. A control portion controls electric power to the heater such that the temperature detected by the temperature detection portion is maintained at a predetermined control target temperature. An obtainment portion obtains image information for forming the unfixed toner image. The control target temperature is set, based on the image information, for each of a plurality of regions defined by dividing the recording material in the conveying direction.

摘要： A diagnostic system may comprise an image forming apparatus that forms a diagnostic image on a sheet and an image capturing apparatus that captures an image of the sheet on which the diagnostic image is formed and which has been discharged from the image forming apparatus, and outputs the image captured as a sheet image. The image capturing apparatus may make a diagnosis for a component of the image forming apparatus based on a position of an image deficiency in the sheet image, and output a diagnosis result for the component of the image forming apparatus.
